Source Lateral Tee (Y-Tee) from verified mills, manufacturers and stockists on MetalMitra. Options span seamless, welded and fabricated, produced to MSS SP-75 / manufacturer standard, and every order can ship with an EN 10204 3.1 certificate.
Through MetalMitra you can source Lateral Tee (Y-Tee) in stainless steel, carbon steel, alloy steel, duplex, nickel alloy and other grades, across a broad range of sizes and pressure ratings.
A lateral tee has a branch at 45° (or another angle) to the run, giving a smoother flow path than a 90° tee for slurry, drainage and solids handling.
Buttweld fittings are bevelled at the ends and welded directly to the pipe, giving a continuous, leak-resistant joint with a smooth bore and low pressure drop. They are the standard choice for process piping above 2" NB and for high-pressure, high-temperature service.
What you can source
- Elbows — 45°, 90° and 180° long and short radius elbows.
- Tees & Crosses — Equal and reducing tees and crosses.
- Reducers — Concentric and eccentric reducers.
- Stub Ends & Caps — Lap joint stub ends and pipe end caps.
Key properties
- 45° Branch — Lower turbulence than a 90° tee.
- Solids Handling — Suitable for slurry and drainage lines.
- Smooth Flow — Butt-welded joints for a smooth bore and minimal pressure drop.
- High-Pressure Ready — Rated for high-pressure, high-temperature service.
